Isaac is a male given name of Hebrew origin that means “he laughs” or “he will laugh.” The moniker has maintained a steady and admired presence across generations of parents choosing classic names for boys.
Meaning and Origin
The name Isaac is derived from Judaism and has long served as a given name among Jewish, Christian, and Muslim societies, generally in reference to the biblical figure. Isaac was one of the three patriarchs in the Hebrew Bible, whose story is told in the book of Genesis. According to the account in Genesis, the name is explained as referring to his mother Sarah’s laughing when she was told she would have a son at her old age.
From an etymological perspective, the name originates from the Hebrew יצחק (Yiṣḥāq), literally translating to “he laughs” or “he will laugh.” The verb is masculine, however, perhaps due to its use as a boy’s name. Over centuries of linguistic transmission, the Hebrew name moved into Ancient Greek as Ἰσαάκ (Isaák), subsequently passed into Latin as Isaac, and entered Middle English as Ysaac. The name is also transliterated from Yitzhak and Yitzchok.
